本文通过分析左右手传输线的后向波理论，提出了一种基于复合左右手传输线的有源漏波阵列天线。该天线的有源辐射单元部分采用左右手传输线结构，通过添加有源放大器和移相器，在传输方向上可以实现前后向波束大范围扫描，在组阵方向实现波束相扫，整个阵列实现两维电扫功能。仿真与实验结果吻合良好，表明该设计方法的正确性和可行性。

An active leaky-wave array antenna based on composite right/left handed transmission line （CRLH TL） is presented on basis of analyzing backward wave theory of CRLH TL. The active radiation element of this antenna adopts right-left handed transmission line structure, and by adding active amplifiers and phase shifteLs, beam scanning in front/backwards of large scope can be implemented in transmission line, and beam phase scanning in com- bination of array direction is implemented. Therefore, the whole array can implement two dimensional electronic scanning function. The high agreement of simulated and experimented results show the correctness and feasibility of this design method.
